Fractional corner charges in a 2D super-lattice Bose-Hubbard model
Julian Bibo, Izabella Lovas, Yizhi You +2
We study a two dimensional super-lattice Bose-Hubbard model with alternating hoppings in the limit of strong on-site interactions. We evaluate the phase diagram of the model around…
Non-local emergent hydrodynamics in a long-range quantum spin system
Alexander Schuckert, Izabella Lovas, Michael Knap
Generic short-range interacting quantum systems with a conserved quantity exhibit universal diffusive transport at late times. We employ non-equilibrium quantum field theory and se…
Non-equilibrium time evolution and rephasing in the quantum sine-Gordon model
D. X. Horvath, I. Lovas, M. Kormos +2
We discuss the non-equilibrium time evolution of the phase field in the sine-Gordon model using two very different approaches: the truncated Wigner approximation and the truncated…
Can supercooling explain the HBT puzzle?
L. P. Csernai, M. I. Gorenstein, L. L. Jenkovszky +2
Possible hadronization of supercooled QGP, created in heavy ion collisions at RHIC and SPS, is discussed within a Bjorken hydrodynamic model. Such a hadronization is expected to be…
